Please make sure you have the latest version of the guides and that you do not have any out of date addons enabled.

I'm using Zygor 5.0.10928 and I didn't have this issue last night with the previous version of Zygor. I just updated today before I logged on.

[4b0d7376]

I just unloaded all addons except Bugsack/Buggrabber and Zygor. Then I tried again. Still getting error while using Zygor 5.0.10928

What are you doing when this bug shows up? What kind of step is showing? Is this easy to reproduce?

[w477y1877]

I made a thread about this this morning, and I've seen at least one other since I posted mine. Everytime you click a flightmaster you get a Lua error and you cannot fly anywhere unless you disable the guide. Mine was fine too, until the latest update.

[ZG Support 1]

Does this error show up only when you try to take a flight? Does it show up when you open the flight map or when you actually click on the destination? Does it happen when the arrow does not tell you to take a flight? If you close the guide viewer and arrow does the error still happen?

Just working on finding a way to reliably reproduce the error so the dev team can find the problem faster.

[w477y1877]

It happens when you access the flight map. The lua error shows and then you can't click any flight destinations.

[ZG Support 1]

Ok, I will make sure the dev team are aware of it to get it fixed as quickly as they can.

[Zygor Dev 1]

Did the error perhaps appear when you chose to fly right after logging in, before ZGV fully initialized? We'll patch this not to crash with an error, of course, but visiting new flightpoints (as you seem to have done) won't register with the addon if it didn't have a few seconds to initialize first.

[4b0d7376]

I get this error when clicking on a Flightmaster to get the Flightpoint OR if I already have that particular flightpoint, then I get it when trying to choose a destination to fly to.

[4b0d7376]

Oh, I misread your question. No, I was logged in for quite a while. Everything was loaded fine. I had used the guide to do questing up to the point where the guide told me to get a flightpoint when I first had the error come up.

[4b0d7376]

Just so you know, I "downgraded" with a backup to Zygor 5.0.10919 and this no longer happens. So something has changed in the last patch.

[Zygor Dev 1]

Please try with the newest version, 5.0.10934. If it still happens, just the top ~10 lines of the error message will suffice in this case.
